●●(2sin 7cos 7cos 14 cos28 cos56 / 2sin7 
2 x sin7° x cos7°) x cos14° x cos28° x cos56° ÷ (2 x sin 7°) 


●●1/2 x 1/2 x (2 sin 14° x cos 14°) x cos 28° x cos 56° ÷ sin 7° 

●● 1/4 x 1/2 x (2 x sin 28° x cos 28°) x cos 56° ÷ sin 7° 


●● 1/8 x 1/2 x (2 x sin 56° x cos 56°) ÷ sin 7° 

●● 1/16 x sin 112° ÷ sin 7°

= 1/16 x sin(180° ─ 68°) ÷ sin 7° 

●● 1/16 x sin 68° ÷ sin 7° 

HOPE IT HELPS U...!!❤❤❤❤❤⭐⭐⭐⭐
